Superman, also called The Man of Steel, is one of the most influential superheroes of DC comics, and superhero comics at large. Superman was created by Joe Shuster (born in Canada) and US wrter Jerry Siegel in 1932 for DC Comics, and first appeared in Action Comics #1 in June 1938. After that Superman made stints in various forms: from radio serials and television programs to films, video games and newspaper strips. In the comics, Superman, whose birth name is Kal-El (he was born on the alien planet Krypton before being rocketed to Earth as an infant by his scientist father moments before the planet's destruction), poses as journalist Clark Kent. Some of Superman's arch enemies include industrialist Lex Luthor, Mr. Mxyzptlk, Bizarro (a "reverse" version of Superman) and Doomsday, who once supposedly killed Superman (he came back to life later on).
